Abstract: Case 2539 ABSTRACT OF THE DISCLOSURE     Electrical devices suitable for use in difficult environments include portions thereof made from material selected from the group comprising zirconium and zirconium alloy.  The component parts are manufactured in an electrically non-insulated condition and pre-assembled in potentially mutual shortcircuited relation, and then processed in order to develop a zirconia insulating layer, even in the case where intimate shortcircuiting contact exits.  In some instances at least, there is no imperative need to roughen the surfaces prior to formation of the zirconia protective layer.  The thickness of the layer can be controlled to enhance the security of interfitted parts.

Abstract: TRIGGER SWITCH AND LOCK MECHANISM THEREFORE          Abstract of the Disclosure A trigger switch and lock mechanism therefore to be mounted in the handle of a drill housing for activating a motor of a drill wherein the trigger switch includes a speed control circuit carried on a circuit board.  A trig-ger is slidably disposed in mounting brackets affixed on the circuit board.  A locking member is slidably connected in one of the mounting brackets and is shiftable into con-tact with the trigger so as to lock the trigger in depressed position so that once the switch has been activated it will be locked in the "on" position at the selected speed setting.          A spring is connected to the locking member to release the locking member from engagement with the trigger upon subse-quent trigger depression to place the switch in the "off" position.    The locking member and trigger have correspondingly high friction contact surfaces.   The locking member may have a camming portion which coacts with the bracket to cause a wedge-lock action at the trigger contact surface which is releasable only upon sub-sequent trigger depression resulting in release of the lock-ing member and deactivation switch upon the trigger load spring biasing the trigger to the "off" position.

Abstract: ABSTRACT OF THE DISCLOSURE           A circuit for controlling the reverse recovery current in a controlled rectifier.  The primary winding of a saturable reactor is connected in series with the controlled rectifier. A diode in parallel with a resistor is connected in circuit with the secondary winding of the saturable reactor. The diode is poled to provide a low impedance in the reactor secondary when current flows through the primary winding and through the forward direction of the controlled rectifier.  The reverse recovery current of the controlled rectifier flowing through the primary winding of the reactor causes current in the secondary winding to flow in the reverse direction of the diode.  The value of the resistor as reflected into the saturable reactor primary circuit limits the magnitude of the reverse recovery current.

Abstract: LOCATOR FOR VERTICAL REINFORCING BARS          ABSTRACT OF THE DISCLOSURE: A  fixture for precisely locating the vertical reinforcing steel bars in a hollow block wall at the exact positions specified by the design engineer.          The fixture comprises one or more steel wires forming a horizontal sup-porting structure that is adapted to be laid on the top surface of the blocks at various levels as the blocks are being laid. In the preferred form, the horizontal supporting structure is a ladder-like structure made up of two laterally spaced, parallel wires connected together at intervals by cross wires. Certain of the cross wires have circular rings formed therein or attached thereto, and all of the cross wires have downwardly projecting legs that extend down into the cavities of the hollow blocks and engage the inner surfaces thereof to locate the ladder-like structure with respect to the blocks. The rings are positioned in vertical alignment with respect to one another, and the vertical bars are lowered into the block cavities from the top of the wall, with the bar being inserted through each of the rings, in turn, at the different levels. After the steel bars have been placed, the cavities are filled with cement grout, which embeds the bars. The rings can be located at various points to locate the vertical steel bars at the exact positions specified by the design engineer, and in some cases, one set of rings may be provided to receive the stub steel bars projecting up-wardly from the concrete footing, while another set of rings receives the vertical reinforcing bars.
